The solution to that, as has been mentioned, is to not use a bulb, you use an LED or laser diode. My mention of a bulb was simply an example of a device for converting electrical energy to optical (well, photonic) energy. In reality, 44.1kHz is such a slow switching speed for any kind of signalling (fibre optic or electrical) as to be truly "simple" with todays technology. I'm not going to get into the arguments about jitter (I've had enough of those already) but to make a statement that "electrical to optical conversions are harder than electrical to magnetic ones" is vague and meaningless. And to use that as a reason why a HDD is "better" than a CD is equally absurd. First you have to define "better", and depending on that definition you'll get a different answer. -- radish ------------------------------------------------------------------------ radish's Profile: http://forums.slimdevices.com/member.php?userid=77 View this thread: http://forums.slimdevices.com/showthread.php?t=18772 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
